Explanation:

PART B

1. Brief Explanations: Colas are liquid, so volume unit milliliter (mL) is appropriate for bottle volume.

• Answer: milliliter

1. Brief Explanations: Mass of a bowling ball, kilogram (kg) is a suitable unit for its mass.

• Answer: kilogram

1. Brief Explanations: Length of a housefly, millimeter (mm) is appropriate for small length.

• Answer: millimeter

1. Brief Explanations: Mass of a paperclip, gram (g) is a common unit for small mass.

• Answer: gram

1. Brief Explanations: Volume of cough syrup, milliliter (mL) is used for liquid volume.

• Answer: milliliter

• Answer: meter

1. Brief Explanations: Time unit, second (s) is used here as 642,000 seconds and 10.7 minutes relate, so second.

• Answer: second

PART C

1. \(1000\space mg=\) \(\boldsymbol{g}\)

**:

Step1: Recall conversion factor (\(1\space g = 1000\space mg\))

\(1000\space mg\times\frac{1\space g}{1000\space mg}\)

Step2: Simplify

\(= 1\space g\)

**:

Step1: Recall conversion factor (\(1\space Kg = 1000\space g\))

\(198\space g\times\frac{1\space Kg}{1000\space g}\)

Step2: Simplify

\(= 0.198\space Kg\)

**:

Step1: Recall conversion factor (\(1\space cm = 10\space mm\))

\(8\space mm\times\frac{1\space cm}{10\space mm}\)

Step2: Simplify

\(= 0.8\space cm\)

Answer:

\(1\)

2. \(198\space g=\) \(\boldsymbol{Kg}\)
